BalladA popular narrative song passed down orally. In the English tradition, it usually follows a form of rhymed (abcb) quatrains alternating four-stress and three-stress lines. Folk (or traditional) ballads are anonymous and recount tragic, comic, or heroic stories with emphasis on a central dramatic event; examples include “Barbara Allen” and “John Henry.” Beginning in the Renaissance, poets have adapted the conventions of the folk ballad for their own original compositions. Examples of this “literary” ballad form include John Keats’s “La Belle Dame sans Merci,” Thomas Hardy’s “During Wind and Rain,” and Edgar Allan Poe’s “Annabel Lee.” Browse more ballads.

BalladeAn Old French verse form that usually consists of three eight-line stanzas and a four-line envoy, with a rhyme scheme of ababbcbc bcbc. The last line of the first stanza is repeated at the end of subsequent stanzas and the envoy. See Hilaire Belloc’s “Ballade of Modest Confession” and Algernon Charles Swinburne’s translation of François Villon’s “Ballade des Pendus” (Ballade of the Hanged).

CanzoneLiterally “song” in Italian, the canzone is a lyric poem originating in medieval Italy and France and usually consisting of hendecasyllabic lines with end-rhyme. The canzone influenced the development of the sonnet.

CarolA hymn or poem often sung by a group, with an individual taking the changing stanzas and the group taking the burden or refrain. See Robert Southwell’s “The Burning Babe”. Many traditional Christmas songs are carols, such as “I Saw Three Ships” and “The Twelve Days of Christmas.”

CoupletA pair of successive rhyming lines, usually of the same length. A couplet is “closed” when the lines form a bounded grammatical unit like a sentence (see Dorothy Parker’s “Interview”: “The ladies men admire, I’ve heard, /Would shudder at a wicked word.”). The “heroic couplet” is written in iambic pentameter and features prominently in the work of 17th- and 18th-century didactic and satirical poets such as Alexander Pope: “Some have at first for wits, then poets pass’d, /Turn’d critics next, and proved plain fools at last.” Browse more couplet poems.

DirgeA brief hymn or song of lamentation and grief; it was typically composed to be performed at a funeral. In lyric poetry, a dirge tends to be shorter and less meditative than an elegy. See Christina Rossetti’s “A Dirge” and Sir Philip Sidney’s “Ring Out Your Bells.”

It must have been an awful sight, To witness in the dusky moonlight, While the Storm Fiend did laugh, and angry did bray, Along the Railway Bridge of the Silv’ry Tay, Oh! ill-fated Bridge of the Silv’ry Tay, I must now conclude my lay By telling the world fearlessly without the least dismay, That your central girders would not have given way, At least many sensible men do say, Had they been supported on each side with buttresses, At least many sensible men confesses, For the stronger we our houses do build, The less chance we have of being killed.

EpicA long narrative poem in which a heroic protagonist engages in an action of great mythic or historical significance. Notable English epics include Beowulf, Edmund Spenser’sThe Faerie Queene (which follows the virtuous exploits of 12 knights in the service of the mythical King Arthur), and John Milton’sParadise Lost, which dramatizes Satan’s fall from Heaven and humankind’s subsequent alienation from God in the Garden of Eden. Browse more epics.

EpithalamionA lyric poem in praise of Hymen (the Greek god of marriage), an epithalamion often blesses a wedding and in modern times is often read at the wedding ceremony or reception. See Edmund Spenser’s “Epithalamion.” Browse more epithalamions.

Found poemA prose text or texts reshaped by a poet into quasi-metrical lines. Fragments of found poetry may appear within an original poem as well. Portions of Ezra Pound’sCantos are found poetry, culled from historical letters and government documents. Charles Olson created his poem “There Was a Youth whose Name Was Thomas Granger” using a report from William Bradford’s History of Plymouth Plantation.

FourteenerA metrical line of 14 syllables (usually seven iambicfeet). A relatively long line, it can be found in narrative poetry from the Middle Ages through the 16th century. Fourteener couplets broken into quatrains are known as common measure or ballad meter. See also Poulter’s measure.

Ghazal(Pronounciation: “guzzle”) Originally an Arabic verse form dealing with loss and romantic love, medieval Persian poets embraced the ghazal, eventually making it their own. Consisting of syntactically and grammatically complete couplets, the form also has an intricate rhyme scheme. Each couplet ends on the same word or phrase (the radif), and is preceded by the couplet’s rhyming word (the qafia, which appears twice in the first couplet). The last couplet includes a proper name, often of the poet’s. In the Persian tradition, each couplet was of the same meter and length, and the subject matter included both erotic longing and religious belief or mysticism. English-language poets who have composed in the form include Adrienne Rich, John Hollander, and Agha Shahid Ali; see Ali’s “Tonight” and Patricia Smith’s “Hip-Hop Ghazal.”

Gnomic versePoems laced with proverbs, aphorisms, or maxims. The term was first applied to Greek poets in the 6th century BCE and was practiced in medieval Germany and England. See excerpts from the Exeter Book. Robert Creeley explored the genre in his contemporary “Gnomic Verses.”

Haiku (or hokku)A Japanese verse form of three unrhyming lines in five, seven, and five syllables. It creates a single, memorable image, as in these lines by Kobayashi Issa, translated by Jane Hirshfield:

On a branch floating downriver a cricket, singing. (In translating from Japanese to English, Hirshfield compresses the number of syllables.)

LamentAny poem expressing deep grief, usually at the death of a loved one or some other loss. Related to elegy and the dirge. See “A Lament” by Percy Bysshe Shelley; Thom Gunn’s “Lament”; and Edna St. Vincent Millay’s “Lament.”

LandaysA form of folk poetry from Afghanistan. Meant to be recited or sung aloud, and frequently anonymous, the form is a couplet comprised of 22 syllables. The first line has 9 syllables and the second line 13 syllables. Landays end on “ma” or “na” sounds and treat themes such as love, grief, homeland, war, and separation. See Eliza Griswold’s extensive reporting on the form in the June 2013 issue of Poetry, in which she explains how the form was created by and for the more than 20 million Pashtun women who span the border between Afghanistan and Pakistan.

MadrigalA song or short lyric poem intended for multiple singers. Originating in 14th-century Italy, it became popular in England in the late 15th and early 16th centuries. It has no fixed metrical requirements. See “Rosalind’s Madrigal” by Thomas Lodge.

Mock epicA poem that plays with the conventions of the epic to comment on a topic satirically. In “Mac Flecknoe,” John Dryden wittily flaunts his mastery of the epic genre to cut down a literary rival. Alexander Pope’s “The Rape of the Lock” recasts a petty high-society scandal as a mythological battle for the virtue of an innocent.

Ottava rimaOriginally an Italian stanza of eight 11-syllable lines, with a rhyme scheme of ABABABCC. Sir Thomas Wyatt introduced the form in English, and Lord Byron adapted it to a 10-syllable line for his mock-epic Don Juan.W.B. Yeats used it for “Among School Children” and “Sailing to Byzantium.” Browse more ottava rima poems.

PalinodeAn ode or song that retracts or recants what the poet wrote in a previous poem. For instance, Geoffrey Chaucer’sThe Canterbury Tales ends with a retraction, in which he apologizes for the work’s “worldly vanitees” and sinful contents.

PantoumA Malaysian verse form adapted by French poets and occasionally imitated in English. It comprises a series of quatrains, with the second and fourth lines of each quatrain repeated as the first and third lines of the next. The second and fourth lines of the final stanza repeat the first and third lines of the first stanza. See A.E. Stallings’s “Another Lullaby for Insomniacs.” Browse more pantoums.

RomanceFrench in origin, a genre of long narrative poetry about medieval courtly culture and secret love. It triumphed in English with tales of chivalry such as Sir Gawain and the Green Knight and Geoffrey Chaucer’s “The Knight’s Tale” and Troilus and Criseyde.

RondeauOriginating in France, a mainly octosyllabic poem consisting of between 10 and 15 lines and three stanzas. It has only two rhymes, with the opening words used twice as an unrhyming refrain at the end of the second and third stanzas. The 10-line version rhymes ABBAABc ABBAc (where the lower-case “c” stands for the refrain). The 15-line version often rhymes AABBA AABc AABAc. Geoffrey Chaucer’s “Now welcome, summer” at the close of The Parlement of Fowls is an example of a 13-line rondeau.

A rondeau redoublé consists of six quatrains using two rhymes. The first quatrain consists of four refrain lines that are used, in sequence, as the last lines of the next four quatrains, and a phrase from the first refrain is repeated as a tail at the end of the final stanza. See Dorothy Parker’s “Roudeau Redoublé (and Scarcely Worth the Trouble at That).”

Rondel (roundel)A poetic form of 11 to 14 lines consisting of two rhymes and the repetition of the first two lines in the middle of the poem and at its end. Algernon Charles Swinburne’s “The Roundel” is 11 lines in two stanzas.

SestetA six-line stanza, or the final six lines of a 14-line Italian or Petrarchan sonnet.

SestinaA complex French verse form, usually unrhymed, consisting of six stanzas of six lines each and a three-line envoy. The end words of the first stanza are repeated in a different order as end words in each of the subsequent five stanzas; the closing envoy contains all six words, two per line, placed in the middle and at the end of the three lines. The patterns of word repetition are as follows, with each number representing the final word of a line, and each row of numbers representing a stanza:

SijoA Korean verse form related to haiku and tanka and comprised of three lines of 14-16 syllables each, for a total of 44-46 syllables. Each line contains a pause near the middle, similar to a caesura, though the break need not be metrical. The first half of the line contains six to nine syllables; the second half should contain no fewer than five. Originally intended as songs, sijo can treat romantic, metaphysical, or spiritual themes. Whatever the subject, the first line introduces an idea or story, the second supplies a “turn,” and the third provides closure. Modern sijo are sometimes printed in six lines.

SlamA competitive poetry performance in which selected audience members score performers, and winners are determined by total points. Slam is a composite genre that combines elements of poetry, theater, performance, and storytelling. The genre’s origins can be traced to Chicago in the early 1980s. Since then, groups of volunteers have organized slams in venues across the world. The first National Poetry Slam was held in 1990, and has become an annual event in which teams from cities across the United States compete at events in a host city. For more on poetry slams, see Jeremy Richards’s series “Performing the Academy”. See also poets Tyehimba Jess, Bob Holman, and Patricia Smith.

SonnetA 14-line poem with a variable rhyme scheme originating in Italy and brought to England by Sir Thomas Wyatt and Henry Howard, earl of Surrey in the 16th century. Literally a “little song,” the sonnet traditionally reflects upon a single sentiment, with a clarification or “turn” of thought in its concluding lines.

The Petrarchan sonnet, perfected by the Italian poet Petrarch, divides the 14 lines into two sections: an eight-line stanza (octave) rhyming ABBAABBA, and a six-line stanza (sestet) rhyming CDCDCD or CDEEDE. John Milton’s “When I Consider How my Light Is Spent” and Elizabeth Barrett Browning’s “How Do I Love Thee” employ this form.

Wyatt and Surrey developed the English (or Shakespearean) sonnet, which condenses the 14 lines into one stanza of three quatrains and a concluding couplet, with a rhyme scheme of ABABCDCDEFEFGG (though poets have frequently varied this scheme; see Wilfred Owen’s “Anthem for Doomed Youth”). George Herbert’s “Love (II),” Claude McKay’s “America,” and Molly Peacock’s “Altruism” are English sonnets.

-The curtal sonnet, a shortened version devised by Gerard Manley Hopkins that maintains the proportions of the Italian form, substituting two six-stress tercets for two quatrains in the octave (rhyming ABC ABC), and four and a half lines for the sestet (rhyming DEBDE), also six-stress except for the final three-stress line. See his poem “Pied Beauty.”

-The sonnet redoublé, also known as a crown of sonnets, is composed of 15 sonnets that are linked by the repetition of the final line of one sonnet as the initial line of the next, and the final line of that sonnet as the initial line of the previous; the last sonnet consists of all the repeated lines of the previous 14 sonnets, in the same order in which they appeared. Marilyn Nelson’sA Wreath for Emmett Till is a contemporary example.

Terza rimaAn Italian stanzaic form, used most notably by Dante Alighieri in Commedia (The Divine Comedy), consisting of tercets with interwoven rhymes (ABA BCB DED EFE, and so on). A concluding couplet rhymes with the penultimate line of the last tercet. See Percy Bysshe Shelley’s “Ode to the West Wind,” Derek Walcott’s “The Bounty,” and Omeros, and Jacqueline Osherow’s “Autumn Psalm.”

TrioletAn eight-line stanza having just two rhymes and repeating the first line as the fourth and seventh lines, and the second line as the eighth. See Sandra McPherson’s “Triolet” or “Triolets in the Argolid” by Rachel Hadas.

VerseAs a mass noun, poetry in general; as a regular noun, a line of poetry. Typically used to refer to poetry that possesses more formal qualities.

Verse paragraphA group of verse lines that make up a single rhetorical unit. In longer poems, the first line is often indented, like a paragraph in prose. The long narrative passages of John Milton’s Paradise Lost are verse paragraphs. The titled sections of Robert Pinsky’s “Essay on Psychiatrists” demarcate shifts in focus and argument much as prose paragraphs would. A shorter lyric poem, even when broken into stanzas, could be considered a single verse paragraph, insofar as it expresses a unified mood or thought; see Gail Mazur’s “Evening.”
